Description

Technical Field

[0002] A band saw is a mechanical device used to cut materials. Its main feature is that it uses a band saw blade as a cutting tool. Band saws are usually used to cut metals, wood, plastics and other materials, and are widely used in industrial production and processing fields. Band saws are efficient, precise, and suitable for a variety of materials. They are widely used in metal processing, woodworking, construction, furniture manufacturing and other fields. According to different cutting requirements and material properties, different types of band saws can be selected, such as manual band saws, semi-automatic band saws and fully automatic band saws. Band saw feeding devices are usually used to automatically or semi-automatically feed raw materials into the cutting area of ​​the band saw for cutting or processing. This device can improve production efficiency, reduce labor costs, and reduce safety risks for operators.

[0003] When loading rod-shaped raw materials, the rod-shaped raw materials are usually transported to the cutting area of ​​the band saw machine through two conveyor rollers. However, during the transportation process, there is a lack of a structure to limit the position of the rods, so that the rods may be offset when they are sent to the cutting area, thereby reducing the cutting accuracy. Therefore, we propose a band saw machine feeding device to solve the above problem. Utility Model Content
